This is an online lesson associated with activities during Solar Week, a twice-yearly event in March and October during which classrooms are able to interact with scientists studying the Sun. This activity is scheduled to occur during Monday of...(View More) Solar Week. The lesson introduces the concept of astronomical filters and their connections to imaging different objects in space. Learners will explore perceptions of images as seen using different colors of light, construct a filter wheel, and practice investigating various astronomical images using the filter wheel. This material was designed to highlight how filters are useful to astronomers and show how a real astronomical telescope uses filters to image the Sun. Outside of Solar Week, information, activities, and resources are archived and available online at any time.(View Less)

This is an activity about electromagnetism and the Sun. First, learners will do a KWL activity using six vocabulary words. Next, they will build an electromagnet and investigate how it works. Finally, learners will relate the workings of their...(View More) electromagnet to a Solar Dynamics Observatory magnetogram image of the Sun. Per group of learners, this activity requires materials such as a length of insulated wire, alligator clips, a 2-D-battery holder, two D-batteries, and a nail.(View Less)

This is an activity about the Doppler effect. Learners begin by simulating the noise made by a passing siren. After learning that the change in pitch results from movement, they investigate the definition of frequency, calculate change in frequency,...(View More) and learn how this applies to light and the study of astronomy. This lesson requires a Doppler ball, also referred to as a buzzer ball.(View Less)

This is an activity about the relation between day length and temperature. In one team, learners will create and analyze a graph of hours of sunlight versus month of the year for a number of latitudes. In another team, learners will graph...(View More) temperature versus month for the same latitudes. The teams then compare data and draw conclusions from their analyses.(View Less)

This experimental activity is designed to develop a basic understanding of the interrelationship between temperature and pressure and the structure of a device made to examine this relationship. Resources needed to conduct this activity include two...(View More) canning jars, two large rubber balloons, a heat lamp or lamp with 150 watt bulb, and access to freezer or water and ice. The resource includes background information, teaching tips and questions to guide student discussion. This is chapter 5 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.(View Less)

This activity promotes student understanding of some of the movements that take place when warmer water and cooler water interface, and how differences in densities, resulting from variations in temperature, set molecules of liquids and gases in...(View More) motion. Resources needed for the investigation include a large clear plastic container, a thermometer, metric measuring cup, food coloring, water, and ice. The resource includes background information, teaching tips and questions to guide student discussion. This is chapter 9 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.(View Less)

This experimental activity is designed to develop basic understanding of the relationship between the angle of light rays and the area over which the light rays are distributed, and the potential to affect changes in the temperature of materials....(View More) Resources needed to conduct this activity include a flashlight, cardboard, protractor and ruler. The resource includes background information, a pre-activity inquiry exploration for students, teaching tips and questions to guide student discussion. This is chapter 4 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.(View Less)

This is an activity about magnetic induction. Learners will induce a flow of electricity in a wire using a moving bar magnet and measure this flow using a galvanometer, or Am meter. Through discussion, this activity can then be related to magnetic...(View More) fields in nature. This activity requires use of a galvanometer, bar or cow magnet, and wire. This is the fifth lesson in the second session of the Exploring Magnetism teacher guide.(View Less)

This is an activity about electromagnetism. Learners will use a simple circuit powered by a battery source to investigate the strength of the magnetic field produced by a coil of wire in the circuit. The strength will be indicated by the deflection...(View More) of magnetic compass needles and by the distance a coil of wire was moved by the action of the circuit. This activity requires coils or spools of wire, a knife switch, three magnetic compasses, a source of electricity such as 3 D-cell batteries or an AC to DC power adapter, alligator-clipped wire, and a bar or cow magnet. This is the fourth lesson in the second session of the Exploring Magnetism teachers guide.(View Less)

This is an activity about magnets and magnetism. Learners first make predictions about magnets, such as a list of the types of materials a magnet will pick up, how a magnet can be made, and how a compass can be made. Next, learners test their...(View More) predictions using simple experiments, and, finally, reflect on their predictions. This is the second activity in the Mapping Magnetic Influence educators guide.(View Less)
